Japan has started planning to make a next-generation supercomputer by 2020, which will be 100 times faster than K, the country's latest model.

Officials from the Education, Culture, Sports, Science and Technology Ministry say they will seek funding to design the new machine in its fiscal 2015 budget requests, The Japan Times reported on Friday.

The ministry hopes to use the next-generation supercomputer to develop drugs and enhance disaster prevention by predicting earthquakes and tsunamis, among other purposes, the officials said. They will also shoot for exaflop capability, or 1 quintrillion computations per second.

It is hoped the cost of the new supercomputer will be kept below the 110 billion yen required to develop K, the ministry said, adding where it will be built has yet to be determined.
